He underwent further standard resuscitation EXCEPT that we applied the Inspiratory Threshold Device ( ResQPod ) AND applied Dual Sequential Defibrillation (this simply means we applied 2 sets of pads, had 2 defib machines, and defibrillated with both with only a fraction of one second separating each defibrillation.

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. This young male had ventricular fibrillation during a triathlon. His initial ECG is shown here. He awoke and did well.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. He had multiple cardiac arrests with ROSC regained each time. This patient arrested shortly after hospital arrival. As a result — the history will often be limited to what was known prior to the arrest.

She was unable to be defibrillated but was cannulated and placed on ECMO in our Emergency Department (ECLS - extracorporeal life support). After good ECMO flow was established, she was successfully defibrillated. Here is a case of ECMO defibrillation with near shark fin that was due to proximal LAD occlusion. The K was normal.

Are Some Cardiologists Really Limited by Strict Adherence to STEMI millimeter criteria? I was texted these ECGs by a recent residency graduate after they had all been recorded, along with the following clinical information: A 50-something with no cardiac history, but with h/o Diabetes, was doing physical work when he collapsed.

RBBB in acute STEMI has a very high mortality. Were it not for this prehospital ECG and the cardiac arrest, the diagnosis may have been significantly delayed. Had this happened, the artery may have re-occluded prior to angiography, with resultant recurrent cardiac arrest and/or shock and death.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The below ECG was recorded. What do you think?

The patient was diagnosed with esophageal reflux and was being discharged by the nurse when he had a cardiac arrest. He was defibrillated. Anterolateral STEMI. The formula results in 23.43, just above the 23.4 Here is his post resuscitation ECG: Now the diagnosis is obvious.

If it is STEMI, it would have to be RBBB with STEMI. This ECG pattern may be diagnostic of B rugada S yndrome IF seen in association with: i ) a history of cardiac arrest; polymorphic VT; or of non-vagal syncope; and / or ii ) a positive family history of sudden death at an early age; and / or iii ) a similar ECG in relatives.

If cardiac arrest from hypokalemia is imminent (i.e., to greatly decrease risk (although in STEMI, the optimal level is about 4.0-4.5 As I indicated above, in our cardiac arrest case, after pushing 40 mEq, the K only went up to 4.2 How would you treat?

After the second defibrillation the patient had an organized rhythm: Bradycardic escape/agonal rhythm, with large ST deviations. A repeat ECG was done: Obvious anterolateral wall STEMI. It should have been shocked at least 10 seconds ago. Beats 4, 6, and 7 are narrow, as the rhythm is trying to resume from above the ventricles.

She was defibrillated and resuscitated. It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored.

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab.
